<strong>carbon dioxide<\/strong> (CO2), an indicator of air confinement, <strong>carbon monoxide<\/strong> (CO), an indicator of malfunctioning combustion devices, <strong>particulate matter<\/strong> (PM2.5 and PM10), an indicator of pollution transfer from outdoor air to indoor air, <strong>volatile organic compounds<\/strong> (VOC), an indicator of point emissions and of ventilation efficiency, <strong>formaldehyde<\/strong>, a very volatile compound, classified as carcinogenic, present in many CPE, <strong>temperature<\/strong> and<strong> humidity<\/strong> in the building, <strong>bacterial and fungal flora<\/strong>. There are also other indicators: nitrogen dioxide (NO2), benzene, asbestos, radon, etc.<\/p><p>The FDES include a health declaration section in which indoor air <strong>quality occupies a prominent place<\/strong>. Thus the following emissions or sources of pollution (see Appendix D of the national supplement NF EN 15 804\/CN) must be declared :<\/p><ul><li>Carbon monoxide (CO)<\/li><li>Carbon dioxide (CO2)<\/li><li>Nitrogen and sulphur oxides (NOx, SOx)<\/li><li>Hydrocarbons<\/li><li>Radon and radiation<\/li><li>Volatile Organic Compounds (VOC)<\/li><li>Dust<\/li><li>Viable particles including microorganisms such as small insects, protozoa, moulds, bacteria and viruses<\/li><li>Non-viable particles, such as fibres and respirable and non-respirable airborne particles<\/li><\/ul><p>If the product is not concerned by these emissions, the declarant must put it down in writing when he issues his file. They must be assessed according to the methods defined in appendix E of the national supplement NF EN 15 804\/CN. <strong>The results of this product health characterisation are included in the verification<\/strong> <strong>of the FDES<\/strong> by an independent third-party. They constitute input information in the same way as ventilation, outdoor air quality, etc. to improve IAQ at the scale of the building.<\/p><p>In addition to the environmental information from the LCA, since the beginning, the FDES have included information on the contribution of the product to <strong>health quality<\/strong> of interior spaces and <strong>water<\/strong>, as well as to the <strong>quality<\/strong> <strong>of life<\/strong> in the building (hygrothermal, acoustic, visual and olfactory comfort).<\/p><p><img decoding=\"async\" class=\"mb-0 alignleft wp-image-2834\" src=\"https:\/\/www.inies.fr\/wp-content\/uploads\/2021\/09\/image14.png\" alt=\"Etiquette COV\" width=\"179\" height=\"100\" srcset=\"https:\/\/www.inies.fr\/wp-content\/uploads\/2021\/09\/image14.png 486w, https:\/\/www.inies.fr\/wp-content\/uploads\/2021\/09\/image14-300x168.png 300w\" sizes=\"(max-width: 179px) 100vw, 179px\" \/><\/p><p>The FDES include in particular the &#8220;VOC&#8221; label. Since 1 September 2013 (decree 2011-321), all construction and decoration products made available on the market must bear this label reflecting VOC emission levels.<\/p><p>This label, just as the environmental indicators, is digitised in the INIES database, which now allows users to search for products according to a chosen class.<\/p><p>Since these data are present in the INIES Database, it is time to develop compatible tools to have quality of life indicators in buildings in the near future and thus meet the requirements of the Elan Law.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-6204234 grid-faq-page elementor-section-boxed
